Device and method for processing charging requests

Abstract

The invention provides a device and method for processing charging requests. The device and the method are used for parallelly processing massive concurrent charging processing requests from a same shared account and reducing the processing delay of the charging requests. The method comprises following steps of receiving at least two charging request messages from the same shared account, wherein the charging request messages comprise charging request types and specific numerical values corresponding charging request types; for any one received charging request message, according to corresponding relationships of the charging request types and priorities of reserved groups, selecting a reserved group from an account book reserved quota cache table; determining an operation type according to the charging request type; according to the determined operation type, operating the quota configuration current value and the specific numeral value of the selected reserved group in the account book reserved quota cache table, thus obtaining an operation result; and according to the operation result, adjusting the quota configuration current value of the selected reserved group in the reserved quota cache table of the account book.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a device and method for processing billing requests. Background technique [0002] A shared account means that many users share the resources of the same account. For example, in the IoT (Machine to Machine, M2M) scenario, a shared account covers many Subscriber Identity Module (SIM) cards, and the shared account pays for all SIM cards uniformly. All SIM cards share the resources and balance of the shared account, such shared accounts are Phone 800 and Phone 400, for example. [0003] in such as figure 1 In the charging system of the shared account shown, when the balance management function (AccountBalanceManagementFunction, ABMF) module receives a plurality of charging request messages sent by the online charging function (OnlineChargingFunctionOCF) module through the online charging system interface Rc, the ABMF passes through The load balancer distributes the billing requ...

AI Technical Summary

Problems solved by technology

[0009] In the process of maintaining the database of shared accounts, the billing system needs to write to the database in order to maintain the ACID characteristics of the database (atomicity or indivisibility Atomicity, consistency Consistency, isolation or independence Isolation and persistence Durability) Locking, due to the non-parallel processing feature of the lock, multiple billing requests cannot be processed in parallel, and need to be processed one by one online, so there will be a delay in processing the billing request

Especially when it is necessary to perform high-concurrency reservations or chargebacks on the shared account database, due to the large number of reservation or chargeback requests that need to be processed, the processing response delay is long or timed out, which leads to the failure of the call connection on the core network side to be established Or the established communication connection is interrupted. For the end user, the direct experience is that the phone cannot be connected or the call is interrupted during the call.

[0010] To sum up, when the existing technology is used to process the billing processing request of the shared account and maintain the database of the shared account, since a large number of concurrent billing processing requests cannot be processed in parallel, there will be conflicts in the billing request processing, and the billing request long processing time
